DRIVING WHEEL FOR LOCOMOTIVES, ETC.

Application filed June 22, 1927. Serial No. 200,688.

The objectof my invention is to provide a driving wheel with a large, driving pm and with an opening for an enlarged axle, without weakening the hub of the wheel. This object I' attain by making the driving pin an integral partof an auxiliary hub which is driven into the main hub.

In the accompanying drawing Fig. l is a face view of a driving wheel illustrating my invent-ion;

Fig. 2 is a. sectional plan view'on the line 22, Fig. 1; Fig. 3 is a detached perspective view illustrating the auxiliary hub and integral driv- 5 ing pin; and

Fig. 4 is a View illustrating a modifica tion of the invention,

1 is the centre of a driving wheel for 1000- motives having a rim 2 and a hub 3 connected to the rim by spokes in the present instance. On the wheel centre is the'usual flanged tire 5.

In the hub 3 is an openingfi, into which is driven the supplemental or auxiliary hub 7; Forged or cast integral with this hub is the driving pin 8, as clearly shown in Figs.

2 and 3, and in this supplemental hub is an opening v9 for the axle 10. By this construction, the driving pin 6 can be increased in diameter, as well as the axle 10, without weakening the parts, as the pin is forged or cast integral with the auxiliary hub, and the opening in the hub 3 being elongated and somewhat pear-shaped in the present ini stance provides a substantial seat for the auxiliary hub 7 when driven into position, the peculiar shape of the parts preventing one part turning independently of the other without theuse of keys or other fastenings.

- In Fig. 4 I have illustrated a modifica- 4o tion, in which the auxiliary hub 7 is circular in form and fits a circular opening in the main hub of the wheel. o 7

The pin 8 is cast integral with this auxiliary hub 7 and in the hub is an opening 9 for the axle. In this instance the -aux-' iliaryhub'is driven inthe main hub, and a key may be used if desired. Y

Iclaimr y 1. The combination in a driving wheel 5 for locomotives, etc., of a wheel'centre hav ing a hub provided with an opening; and'a supplemental hub driven into the opening and having a crank pin integral therewith.

2'. The combination in a driving wheel 5 for locomotives, etc., of'a wheel centre-having a hub provided with an opening; an auxillaryhub driven into the opening and having a crank pin integral therewith, said auxiliary hub having an axle opening ad- 6 jacent: the pin; and an axle driven into said opening. I

3. The combination in a driving wheel for locomotives, etc., of a wheel centre haV- ing a hub and an elongated opening therein: v

a supplemental hub shaped to correspond. with the. opening in the main hub and driven therein, said auxiliary hub having an integral crank pin and. an opening adjacent the crank pin for an axle, said open- 7 ing being at the centre of the wheel; and an axle in said opening. I
